Frozen ginger contains safrole, while fried ginger still contains safrole. Because safrole can cause liver cancer, it is not advisable to eat more ginger.

In addition, the toxins produced by rotten ginger can also cause cancer. Some people think that "rotten ginger is not bad", and this idea has no scientific basis. Because rotten ginger will produce more toxins, which will lead to liver cancer and esophageal cancer in severe cases. Therefore, although ginger is good, it should not be overdone. Don't eat rotten ginger.

Spices such as ginger contain safrole, which can cause liver cancer. Excessive consumption can easily lead to excessive gastric acid secretion, flatulence, headache, nausea, vomiting, dyspnea, and even affect liver and kidney function, which is harmful to human health. In the past, we advocated a light diet to keep the original flavor of food, which not only meant less salt and oil in cooking, but also less ingredients such as ginger. Eating more fruits and vegetables can effectively inhibit the combination of safrole and oxidant and reduce its carcinogenic effect. Therefore, after eating ginger and other spices, it is best to eat more fruits and vegetables to reduce the harm of safrole.
